While Others Cultivate, I LVL UP In My Sleep Using The Dungeon System

While walking towards another one of the four towers, Adam's mind was racing and analysing everything he had seen so far, while planning his next moves and solidifying all of his realisations.

He had formed two powerful skills and still needed a bit more time to be completely confident in using them and understand all the key components of the skill, as with the Spinning Spear Strike, he was yet to understand how the Bloodlust Characteristic Integrated with it.

While using the skill, everything was happening so quickly and some of the process was skipped and carried out using only instinct, which although saved him, didn't allow him to completely understand.

With Adam's perceptivity, memory and thinking speed, he was repeating everything that had happened in his battle against the Beast Goblin King and learning from it, while thinking about multiple other things at once.

Continuing to walk slowly, Ava, who could see and hear everything that Adam was thinking, was amazed by all the things that were occurring in his mind at once.

He had already prepared a plan to deal with the Goblin Beasts that were surrounding the Core Part of the Goblin Beast City which involved using his Formicidae Summon, the Giant Ant Queen.

With the Giant Ant Queen, Adam could form a stronghold that would produce many Giant Ant Beasts that were just as powerful as the Giant Ant Queen that was at the same cultivation level as him, but the issue with that was that it would require lots of energy to sustain.

To sustain the Giant Ant Queen and all the Giant Ants it was producing, in order for it to be able to produce enough Giant Ant Beasts, Adam had to sustain the summon while providing it additional Internal Energy.

The amount of Internal Energy that would be used would be very taxing on the body and he would also need to be focused on providing the summon energy, so he would be quite defenceless and vulnerable.

However, if he had his Ethereal Recovery Skill activated at the same time and instructed the Giant Ant Queen to protect where he was, he would be able to have many Giant Ant Beast slaughtering the Goblin Beasts while relaxing and being protected.

It would take some time and the plan would only work if the goblin beasts were still unable to enter the Core Part of the Goblin Beast City after he took out the Goblin Kings, but Adam was still mentally prepared for most other possible circumstances.

Although what was inside the giant castle in the centre of the Goblin Beast City was unknown, it was a great place to hide and use to his advantage against so many Goblin Beasts.

Because of its high energy requirements, and also because he felt that it would be easier and more efficient if he fought alone, Adam hadn't used his Unique Collector Skill so far since he was still scouting the Goblin Beast City and becoming accustomed to the way they fought and functioned.

However, after dealing with the Goblin Kings, which he wanted to do himself he was planning to do so. 

Wanting to defeat the Goblin Kings alone was because, although his summons were powerful and capable, the Goblin Kings surpassed most of them in terms of power and capability and because they could hold him back.

The risk of his summons holding him back while draining his energy, along with Adam being eager to fight the Goblin Kings alone to increase his combat prowess, made it so that Adam hadn't used the Collector Skill so far and wasn't planning to do so until he had taken them down.

However, Adam still knew that his Unique Collector Skill was a godly ability and his most powerful and prised ability that he had learnt to value, but also not rely on.

Adam had also noticed that his summons respected him more when he showed his power and didn't rely on them and use them as pawns, which he had previously done. 

Because of that, Adam's Charisma Stat was steadily improving and he had reached a mutual understanding with all of his summons that he would try to use and communicate with whenever he could.

His Charisma was always a few points higher than it needed to be to control a summon at the same level as him and because of it, his summons showed him complete obedience and respect, while he also treated them well and didn't see them as pawns, but as subordinates.

With his high Charisma Stat, Adam was interested to see just how capable his Charm Skill would be and although it didn't work on the goblin beasts, since they held a lot of hatred towards humans, Adam was curious to test out whether it would work on different beasts in the dungeon.

The castle was so large that it took Adam quite a while to walk from one corner to another where another tower was found, but Adam was still yet to enter the castle.

He was planning to leave that until last and make sure to increase his power and understanding of the floor as much as possible, by taking on the Goblin Kings and searching their towers, before entering the castle.

Adam was interested in facing the Mage Goblin King and the Weapon Master Goblin King, as they would be very interesting to face and each should be skilled in combat rather than relying on raw power alone, while he also wanted to face the Giant Goblin King last, since it would cause the most destruction.

Until Adam had taken whatever he felt was valuable from each of the towers and investigate the castle, he wanted to delay facing the Giant Goblin King.

Since he couldn't use his spiritual sense through the walls of the towers or castle, he had no way to know what Goblin King he was going to face next, so all he could do was wish for the best as he entered the second tower.
